The airport's MoD work includes operational readiness, which builds on a 25-year partnership with the Royal Air Force and Royal Navy to train service personnel on Eurofighter Typhoon jets and Type-45 Destroyer battleships.

The firm's DTVA team also conduct calibration of air traffic and navigation systems for civilian airports and military airbases from London Heathrow to the Falkland Islands.

Its presence at DTVA is a boost to airport bosses, who are continuing to work on offsetting passenger operation losses with plans to turn part of the site into a 400-home estate and an industrial hub, strengthened by existing flights to Amsterdam and Aberdeen.

Chiefs say selling land for housing will generate millions of pounds and help fund new hangars, office space and industrial units, with rent occupants making the airport viable and protecting flights.
